Great Northern Insulation

Great solutions were provided for our needs from our sales person, Phil. We had two different insulation products installed, and had two different crews come for installation. Both did an excellent job and were very professional.
I would recommend!

Excellent customer service from start to finish.

We had Tom & John do our Attic top up. They were very professional, took every precaution to insure everything went as it should and made sure that everything was cleaned up before leaving.

Great job!

We would recommend them to anyone who needs their services and definitely call again for any other work we need done.

We received great service from Jeff and Brendan. They were very courteous ,polite, and were very careful around our plants and bushes. I would gladly tell family and friends about the quality of work performed by Jeff and Brendan from the Woodstock office. Thankyou

I wanted my entire attic done in spray foam with no blown in on top because I have an old house and mice have been known to live in the attic in the insulation. I was given a fair price to do all spray foam to meet the R 40 value and was very happy to avoid having blown in.

Jason handled himself at a professional level! The crew of two arrived when they said they would and were polite and courteous and did a wonderful job.
We would recommend GNI to anyone who is in need of their services.

My first experience was with Eric Swanson, an appraiser , very nice and helpful. He sold us on going with you. The two young men, Marc Betz and Jason Norman, that came to do the job came early. Very happy to have them come early. They were kind, efficient and they cleaned up afterwards. Thank you

Great Service and quick response. Both Marc and Jason who did the work were polite and precise.
They prepped and cleaned up so I didn't have to do a thing.

Good service and friendly staff .
Forgot to clean up the attic area when finished.
Other than that I was very satisfied with the efficient and friendly service,
I think is a great program!

Just got the insulation done at our house which we recently purchased. The 3 guys Scott, Conrad and Stefano who came worked with quiet efficiency and did a good job. They arrived on time and made it a point to clean up after they left. I would definitely recommend this company.

I was quoted by Mike from GN Durham and the boys from Lindsay did a fantastic job. Although they left a hook nailed into my roof (they said it was code but I plan to have them come back to remove it), everything else was fantastic. Great job from the guys especially the spray foamer.
